It delivers 15 kvar of reactive power and carries a 5.67% relative throttling factor — sized for harmonic mitigation on motor drives and power-factor-correction banks in industrial panels. The reactor is wound to thermal class B per IEC 60085 and rated for a 40 °C ambient. Power loss at full load runs 89 W, so it throws some heat into the enclosure — keep ventilation in mind when packing it next to drives or contactors. At 0.219 m wide, 0.179 m tall, and 0.143 m deep, it's a compact footprint for a 15 kvar reactor. Mounting is via the screw terminals (main circuit connection) and the enclosure must be IP00-rated — no ingress protection, so it belongs inside a clean, dry cabinet, not out on the plant floor where coolant spray or dust can reach it. The 5.67% throttling factor (relative impedance) is the key selection number — it tells you the voltage drop across the reactor at rated current. For a 400 V drive input, that's about 22.7 V drop, which is typical for a line reactor sized to limit harmonic current without dragging down the DC bus under load. Resonant frequency is 210 Hz. That's above the 5th harmonic (250 Hz) and below the 7th (350 Hz), so this reactor won't accidentally amplify the 5th or 7th on a six-pulse drive — it's a clean choice for standard VFD applications. Inductance is 0.002 H (2 mH) per phase. At 23.7 A and 50 Hz, that gives you roughly 7.45 Ω of inductive reactance — enough to knock down current spikes from capacitor switching or drive commutation without overheating.","metaTitle":"Siemens SIDAC 4EP4001-4MS00 Filter Reactor, 23.7A, 400V, 3-P","metaDescription":"Siemens SIDAC 4EP4001-4MS00 filter reactor, 3-phase, 23.7A rated, 400V, 50Hz, 15kvar, IP00, screw terminals.
